CS7250B - Digital MEMS Microphone

Description

The CS7250B is a high-performance digital MEMS microphone, offering class-leading total harmonic distortion (THD) performance, excellent SNR, and low power consumption.

The CS7250B supports two operational modes, selected according to the applied clock frequency.

Features

  • High acoustic overload point (AOP, 131 dB SPL).
  • High signal-to-noise ratio (SNR, 66 dB).
  • Low variation in sensitivity (±1 dB).
  • Low current consumption.
  • 650 A (High Performance Mode).
  • 160 A (Low Power Mode).
  • 5 A (Standby Mode).
  • PDM digital audio output.
  • Bottom-port LGA package.
  • 1.8-V supply.
